, 2,512,842 DELIVERY SLIDE FOR LINOTYPE MACHINES Emil Szubzda, New Bedford, Mass. Application October 11, 1946, Serial No. 702,637

The present invention relates to new and useful improvements in typographical machines, and more particularly, to a self-adjusting sliding block for the line delivery slide of the machine.

An important object of the invention is to provide a sliding block including means for creating a steady, gentle pressure at the upper and lower edges of the block in the guide grooves to provide the required friction for the proper operation of the machine.

The present delivery slides for the long fingers of typographical machines wear out very rapidly at the beveled edges of the block due to the fact that the side friction shoe presses against one side of the groove and face of the block, thus causing uneven wear and throwing the sliding block out of alignment with other parts of the machine and resulting in poor service, wasted time and expense for replacement.

Accordingly, it is an object of'the present invention to provide a sliding block for the delivery slide of machines of this character which overcomes the objectionable features usually found in conventional sliding blocks.

A further object of the invention is toprovide a device of this character "of simple and practical construction, which is efficient and reliable in operation, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is an end elevational view of the sliding block.

Figure 2 is a side elevational view thereof.

Figure 3 is a vertical sectional view taken on a line 3-3 of Figure 2.

Referring now to the drawings in detail, wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention, the numeral 5 designates a sliding block generally which is composed of upper and lower block sections 6 and I, the upper edge of the upper section 6 being beveled, as shown at 8, for riding in the upper groove 9 for the delivery slide, and the lower edge of the lower section I is also beveled, as shown at Ill, for riding in the lower groove l l of the delivery slide.

A plurality of rods l2 have their upper ends suitably secured in the upper section 6 of the block and have their lower ends freely positioned 4 Claims. (Cl. 308-3) in bores 13 extending vertically in the lower section 1 of the block. The lower ends of the rods project into the beveled sides Ill of the lower section 1 and the lower ends of the rods are correspondingly beveled, as shown at M, and are exposed at beveledsurfaces I0 of the blocks.

Coil springs l 5 are mounted on the rods [2 between the adjacent edges of the sections 6 and I of the block and exert their tension on the blocks to spread the blocks apart to provide a proper frictional engagement between the beveled edges 8 and I0 and the respective grooves 9'and H.

A pair of adjustable stops [6 are secured to one side of the lower section I of the block, the stops including'a vertical slot I! in which a set screw l8 carried by the lower section of the block is received for securing the'stops in vertically adjusted position, the upper end of the stop having an inwardly projecting flange l9 underlying the lower edge of the upper section 6' of the block. The flange l9 of the stop is set at an adjustment to space the lower edge of the upper section 6 of the block at three-thousandths or four-thousandths of an inch therefrom. The upper section 6- of the block carries the long fingers 20 of the line delivery slide for operation in the usual manner.

The springs l5 function to automatically adjust the sections 6 and I of the blocks in the grooves 9 and II to compensate for wear in the grooves and maintain the blocks in proper alignment in the delivery slide.

It is believed that the details of construction, manner of use and advantages of the device will be readily understood from the foregoing without further detailed explanation.

It is to be understood, however, that even though I have herein shown and described a preferred embodiment of my invention, the same is susceptible of certain changes fully comprehended by the spirit of the invention as herein described, and the scope of the appended claims.

Having thus described my invention, what I claim is:
